Disabling back button in react with react-router v6

In React with React Router v6, the back button can be disabled by utilizing the “useEffect” hook to prevent the user from navigating back using the browser’s back button.

Here’s an example of how you can disable the back button in React with React Router v6:

    
      import { useEffect } from 'react';
      import { useLocation } from 'react-router-dom';
      
      function App() {
        const location = useLocation();
        
        useEffect(() => {
          window.history.pushState(null, document.title, window.location.href);
          window.addEventListener('popstate', handleBackButton);
          
          return () => {
            window.removeEventListener('popstate', handleBackButton);
          }
        }, []);
        
        const handleBackButton = () => {
          window.history.pushState(null, document.title, window.location.href);
        }
        
        return (
          // your app's content
        );
      }
      
      export default App;
    
  

In this example, we’re importing the “useEffect” hook and the “useLocation” hook from the “react-router-dom” library. The useLocation hook gives us access to the current location object, which contains information about the current URL.

Inside the App component, we define the useEffect hook with an empty dependency array ([]). This ensures that the effect is only executed once when the component mounts.

Inside the effect, we use the pushState method of the window.history object to replace the current URL with itself. This effectively removes the previous URL from the history stack, preventing the user from navigating back. We also add an event listener for the “popstate” event, which is triggered when the user presses the back button.

The handleBackButton function is called whenever the user presses the back button. Inside this function, we again use the pushState method to replace the current URL with itself, ensuring that the user stays on the same page.

Finally, we return our App component, which should contain the rest of your application’s content.
